Yikes. Turns out you can send a plaintext radio signal to cause any train in the USA to do an emergency break. The original 'security' was just a checksum, no encryption or authentication. Reporting this took them 12 years (!) because the vendor dismissed it initially www.cisa.gov/news-events/...

It’s also terribly insecure as implemented. The trusted peers can be trivially intercepted an adversary can inject themselves into a trusted chat

Being an identical twin has its perks, like easy biometrics testing. Most vendors sensitivity isn’t as good as I hope

I've just been told that John Young of Cryptome.org passed away last week.

#Cryptome was foundational, and a predecessor to organizations like @ddosecrets.com and #Wikileaks.

RIP, John.

My contempt for anyone involved with this drivel knows few limits. Conflating issues and fear mongering because a Chinese company dared to publish an actual open model:

And trying to talk about copyright after training in Libgen.

Hypocrisy, lies, grifting :-(

A while back I was helping examine the security of the Starlink terminal and found a very obvious bug in the bootloader that was only unexploitable due to the memory layout of the terminal. Critical infrastructure shouldn't depend on Starlink without a shitload of auditing.
